Version 4.8.0

Released: 2026-07-24

Added

ps restart command to restart your app's processes. By default it does a graceful, zero-downtime rolling restart (spins up replacement containers before stopping the old ones); add --force to immediately stop the running containers and let them relaunch.
version check command to check if a newer CLI version is available.
version update command to download and install the latest CLI version from GitHub releases.
shell --live/ps exec --live now show each process's size (CPU/memory) in the selector, and print an advisory naming the process and its size after connecting.

ps resize no longer fails on apps that have never had a successful release.
shell now only uses a login shell (bash -l) for buildpack apps, avoiding cases where it clobbered a PATH set by a Dockerfile-based app's image.
selfupdate now errors clearly when a downloaded binary exceeds the size limit, instead of silently truncating it to a confusing checksum mismatch.
Commands other than auth no longer fail with a raw SDK error when the local ~/.aws config has a partial/incomplete default profile.
